2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology. For dual channel con fi guration,
you always need to install identical (the same brand, speed, size and chip-type)
DDR3 DIMM pair in the slots of the same color. In other words, you have to install
identical DDR3 DIMM pair in Dual Channel A (DDR3_A1 and DDR3_B1; Red
slots; see p.4 No.8) or identical DDR3 DIMM pair in Dual Channel B (DDR3_
A2 and DDR3_B2; Black slots; see p.4 No.9), so that Dual Channel Memory
Technology can be activated. This motherboard also allows you to install four DDR3
DIMMs for dual channel con
fi
guration, and please install
identical
DDR3 DIMMs in
all four slots. You may refer to the Dual Channel Memory Con
fi
guration Table below.
Dual Channel Memory Con fi gurations

For the con
fi
guration (3), please install
identical
DDR3 DIMMs in all four
slots.
1. Please install the memory module into the black slot (DDR3_A2
and DDR3_B2) for the fi rst priority.
2. If you want to install two memory modules, for optimal compatibility
and reliability, it is recommended to install them in the slots of the
same color. In other words, install them either in the set of red slots
(DDR3_A1 and DDR3_B1), or in the set of black slots (DDR3_A2
and DDR3_B2).
3. If only one memory module or three memory modules are installed
in the DDR3 DIMM slots on this motherboard, it is unable to activate
the Dual Channel Memory Technology.
4. If a pair of memory modules is NOT installed in the same Dual
Channel, for example, installing a pair of memory modules in
DDR3_A1 and DDR3_A2, it is unable to activate the Dual Channel
Memory Technology .
5. It is not allowed to install a DDR or DDR2 memory module into
DDR3 slot; otherwise, this motherboard and DIMM may be dam-
aged.
6. If you adopt DDR3 2100 memory modules on this motherboard, it is
recommended to install them on DDR3_A2 and DDR3_B2 slots.
